“…The incidence risk of lung cancer, in Italy, was higher among people of low income (1.81 times in men) (Faggiano et al, 1994). For men in Finland it was 3.07 times higher (Pukkala, 1995) and for men in New Zealand it was 3.07 times higher (Blakely et al, 2011). …”

“…However, the incidence risk of rectal cancer was 87% of the mean among men in Ontario, Canada, and 94% in men and 98% in women in the U.S., indicating that the risk was lower among people in the high income group (Boyd et al, 1999;Mackillop et al, 2000). The incidence risk of cervical cancer was higher among low-income women in Australia (1.33 times) (Yu et al, 2008) and New Zealand (1.35 times) (Blakely et al, 2011). The incidence risk of cervical cancer was lower among high-income women in Ontario, Canada (0.71 times) and in the U.S. (0.69 times) (Mackillop et al, 2000).…”

Background: Economic status is known to be directly or indirectly related to cancer incidence since it affects accessibility to health-related social resources, preventive medical checkups, and lifestyle. This study investigates the relationship between cancer incidence and family income in Korea. Methods:Using the Korean National Health Insurance cancer registration data in 2009, the relationship between their family income class and cancer risk was analyzed. The age-standardized incidence rates of the major cancers were calculated for men and women separately. After adjusting for age, residential area, and number of family members, cancer risks for major cancers according to family income class were estimated using a logistic regression model. Results: In men, the risk of stomach cancer for Income Class 5 (lowest) was 1.12 times (95% CI 1.02-1.23) higher than that of Income Class 1 (highest), for lung cancer 1.61 times (95% CI 1.43-1.81) higher, for liver cancer 1.22 times (95% CI 1.08-1.37) higher, and for rectal cancer 1.37 times higher (95% CI 1.18-1.59). In women, the risk of stomach cancer for Income Class 5 was 1.22 times higher (95% CI 1.08-1.37) than that for Income Class 1, while for cervical cancer it was 2.47 times higher (95% CI 2.08-2.94). In contrast, in men, Income Class 1 showed a higher risk of thyroid cancer and prostate cancer than that of Income Class 5, while, in women the same was the case for thyroid cancer. Conclusions: The results show the relationship between family income and cancer risk differs according to type of cancer.

“…Overall, a high-grade poorly differentiated tumour was found in 51.7% of fn women compared with 36.5% of aom women, and negative hr status was found in 29.9% of fn women compared with 21.0% of aom women. However, many other factors-such as changes in reproductive behaviour; lifestyle factors such as diet, alcohol use, and physical activity; differences in access to health care (delay to treatment or type of treatment received); and the presence of comorbidities-likely contribute to mortality differences 40,45 .…”

“…First, cancer incidence rates were obtained from the Ministry of Health long-term trends and future projections in NZ 2,3 and the Cancer Trends study (a record linkage study of census and cancer records). 4,8 Particularly, the Māori:non-Māori rate ratios from the Cancer Trends study were combined with the overall projected rates (by sex and age) and the distribution of the population by ethnicity to give the necessary incidence rates by age. 9 Second, cancer survival or, more exactly, excess mortality 10,11 by age, sex and ethnicity was estimated using cancer registrations linked to mortality data during 2002-06, and then converted into probabilities of dying from cancer.…”

As cardiovascular disease incidence and mortality have steadily declined over the past 30-40 years, the relative burden of disease due to cancer has increased. In 2009, cancer was the leading cause of mortality in New Zealand (NZ) at ICD chapter level, accounting for about 30% of the total number of deaths.1 The age standardised rate for all cancer sites combined steadily increased post World War II, but is now stable (and possibly decreasing).2-4 However, there is notable heterogeneity by cancer sites (e.g. stomach cancer rates decreased over time and haemopoietic cancers increased). 2Burden of disease studies aim to estimate the burden of each major disease for a given country or region of the world at a given time using a composite measure of mortality and morbidity, the disability adjusted life year (DALY).5 A burden of disease study has previously been conducted in NZ for 1996, and found that cancers contributed 20% of the total burden of disease, second only to cardiovascular diseases at 24%. 6A DALY represents the loss of one year of healthy life, whether it is due to premature death or living in a state of less than full health, or a combination of both. In practice, they are calculated as the sum of years of life lost (YLLs) and years of life lived with disability (YLDs). YLLs capture life lost due to premature death from the disease. YLDs are equivalent to years of life lost as a result of living in health states other than full health, where disability weights (DW) are used to quantify the decremental loss of health.This paper aims to: estimate the burden of disease in DALYs arising from incident cancer cases diagnosed in 2006 for 27 cancer sites and show how the cancer DALY differences by sex and ethnicity vary from differences in incidence rates of cancer alone. MethodsWe modelled single year age groups (0-100 years), sex (males and females) and ethnicity (Māori and non-Māori) in terms of incidence, survival and background mortality. Due to the good quality of NZ cancer datasets, and the intended migration of this work into costeffectiveness modelling, a prospective method or incidence approach of calculating DALYs was used. That is, rather than estimating the cross-sectional burden for all prevalent cancer cases in 2006, we estimated the future burden arising from cancers diagnosed in 2006. respectively, sexes pooled).
